Hi guys! I'm currently looking for a way to convert anime subs and video in the mkv format to a more mainstream format such as .avi or .mp4 so I can watch them on my shitty phone. Any helpful links/tips you guys have? I already tried just changing the extension name. That obviously didn't work. And all the softwares that I tried are pretty much scams. Failing this, do you know where I would be able to get a few subbed episodes of Danshi Koukousei no Nichijou directly in the .mp4 or .avi formats? Thanks in advance!
